title: Evaluation of possible prognostic factors for the success, survival, and failure of dental implants.
abstract: OBJECTIVE
  To analyze the prognostic factors that are associated with the success, survival, and failure rates of dental implants.
  
  
  METHODS
  Data including implant sizes, insertion time, implant location, and prosthetic treatment of 1656 implants have been collected, and the association of these factors with success, survival, and failure of implants was analyzed.
  
  
  RESULTS
  The success rate was lower for short and maxillary implants. The failure rate of maxillary implants exceeded that of mandibular implants, and the failure rate of implants that were placed in the maxillary anterior region was significantly higher than other regions. The failure rates of implants that were placed 5 years ago or more were higher than those that were placed later.
  
  
  CONCLUSIONS
  Anterior maxilla is more critical for implant loss than other sites. Implants in the anterior mandible show better success compared with other locations, and longer implants show better success rates. The learning curve of the clinician influences survival and success rates of dental implants.
